ELEVATlNG BRICK-CAR.

SPECIFICATION forming part of Letters Patent N0. 757,710, dated April19, 1904. Application filed April 9, 1903. Serial No. 151,905 (Nomodel.)

To all whom it may concern:

Be it known that we, ANDREW J. ZILKER,

ALBERT L. TIDM'ARSH, and CHARLES J. ARM- STRONG, citizens of the UnitedStates, residing at Austin, in the county of Travis and State of Texas,have invented a new and useful Elevating Brick-Car, of which thefollowing is a specification.

The invention relates to improvements in elevating brick cars or trucks.

The object of the present invention is to improve the construction ofelevating brick cars or trucks and to provide a simple, inexpensive, andefficient car or truck designed for use in a brick-yard for carryingbricks from a machine to a yard, kiln, or drier and from yard or drierto kiln or for otherwise handling bricks or other were and adapted to berun beneath a pallet containing bricks and elevated to raise the palletfrom its supports to permit the same and its contents to be conveyed tothe desired point.

A further object of the invention is to provide a car of this characterwhich will have its elevating frame arranged close to the ground toenable a large number of bricks to be conveniently loaded on it.

Also the invention has for its object to provide a brick-car in whichthe mechanism for raising and lowering the upper frame may. be operatedat either end of the car to avoid turning the latter end for end and toobviate the necessity of providing turn-tables and transfer-cars forthat purpose.

With these and other objects in view the invention consists in theconstruction and novel tion of an elevating-car constructed inaccordance with this invention, the upper frame being lowered. Fig. 2 isa plan view. 3 is a side elevation, the upper frame of the brickcarbeing elevated. Fig; 4: is a longitudinal sectional view, the partsbeing arranged as illustrated in Fig. 1. Fig. 5 is a' horizontalsectional view. Fig. 6 is an enlarged detail sectional view illustratingthe ;manner of mounting the slidable wedges for raising and lowering theupper frame of the car. Fig. 7 is a transverse sectional view of thesame. Fig. Sis a horizontal sectional view on the line 8 8 of Fig. '7.

Like numerals of reference designate corresponding parts in all {hefigures of the drawings.

1 designates a lower or "truck frame provided with front and rearbearings or jour.

rial-boxes for the reception of front and rear axles 2 of wheels 3,which may be flanged, as illustrated in Figs. 2 and 5 of the drawings,when the car is designed to run upon a track A; but the flanges may beomitted and the car may be constructed to run upon the ground similar toan ordinary brick-carrying truck.

The bearings 5, which maybe constructed in any desired manner, arepreferably arranged to receive the axles at points between the wheels,as shown, and the lower frame 1 is mounted directly upon the axles toprovide a low truck to facilitate handling a large load of bricks orother material.

The lower frame 1 is composed ofchanneliron sides 6 and connectingtransverse end' bars 7, provided with central outwardly-extendingbifurcated arms 8, forming supports for operating-levers 9, hereinafterdescribed, for raising and lowering an upper frame 10. The channel-ironsides 6, which are provided with horizontal flanges 11, form guides orways for movable antifriction devices which support reciprocatory wedges12. The antifriction devices consist of a series of antifriction rollersor wheels 13, arranged within an oblong frame 14 and connected with thesame by pivots or spindles 15, extending through the rollers or wheelsand through suitable perforations of the sides of the oblong frame, asclearly illustrated in Figs. 6 and 7 of the drawings. The rollers arearranged upon longitudinalribs or ridges 16, spaced apart, as clearlyshown in Fig. 7, and forming tracks for the antifriction devices,whichare limited in their movement by stops 17 The stops 17 preferablyconsist of L-shaped plates bolted to the bottoms of the channel-bars 6and extending upward to provide abutments for the ends of the oblongframe 1 1, as clearly shown in Fig. 6. I a

The wedge 12, which preferably consists of an open frame, has a lowerhorizontal edge or face to rest upon the rollers or wheels, and it ispreferably flanged at the bottom, as shown. The wedges present inclinedupper faces 18 to antifriction rollers or wheels 19 of the upper. frame10, which is provided at opposite sides with channel bars or beamshaving depending side flanges and presenting flat upper faces to receivethe pallets. 'The antifriction rollers or wheels 19 are arranged withinvertically-movable slides 20, consisting of flanged brackets andcomposed of opposite side flanges, a vertical connecting flange orweb,and ahorizontal top flange which is bolted to the top frame, asshown at 21. The antifriction roller or wheel 19 is arranged between theside flanges of the vertically-movable slide and is connected with thesame by a spindle 22, which extends through the roller or wheel 19 andthrough the side flanges of the slide. The vertically-movable slides arearranged in ways of upright stationary guides 23, provided at the bottomwith perforated webs or cars 24, which are bolted to the flanges 11 ofthe channel-bars of the lower frame The upright guides are provided withparallel vertical flanges 25, which receive the vertically-movableslides. The stationary guides extend across the ways formed by thechannel-bars of the lower frame and are provided with openings orbifurcations at their bottoms to permit the wedges to move outward tothe position illustrated in Fig. 3 of the drawings.

When the wedges are moved outward from the position shown in Fig. 4 tothat illustrated in Fig. 3, the upper frame is elevated and is adaptedto lift a pallet from its support, and when the wedges are moved inwardthe upper frame will be lowered to the position shown in Fig. 1 -toenable the car to deposit a pallet upon suitable supports. The upperframe is also adapted to receive a suitable platform or pallet forenabling bricks or other. material to be loaded upon the car.

The upper faces of the wedges are provided ,with inner and outer orupper and lower seats 26 and 27, preferably curved, as shown, andadapted to receive the antifriction rollers or wheels 19 when the wedgesare at the limit of their movement in either direction. The inner endsof the wedges are provided with upwardly-projecting ears 28, preferablyformed integral with plates 29 and adapted to receive transverse rods 30for connecting the wedges at the opposite sides of the car. The plates29 are secured by bolts 31 or other suitable fastening devices to theinner ends of the wedges 12; but any other form of ear may be employed.Each rod is connected with the end operating-levers 9 by bars 32 and 33,the bar 32 being located above the lower frame and extending outwardfrom the inner end of the wedge to the upper end of the near lever 9.The other bar 33 extends inward from the inner end of the adjacent wedgeand downward at an inclination and passes beneath the axle at the otherend of the car, being connected with the lower end of the operatingleverat that end of the car. The operatinglevers 9 are fulcrumed betweentheir ends by pivots 3a or other suitable fastening devices in thebifurcations of the arms 8, and their terminals are perforated for thereception of pivots 35 and 36 for connecting the levers with the outerends of the bars 32 and 33. The outer ends of the inclinedconnecting-bars are angularly bent at 37 to enable them to clear theadjacent axles when the upper frame of the car is elevated. Theconnecting-bars 32 and 33 are located at the center of the car, theinner ends of the connecting-bars 32 being forked to straddle the innerends of the connecting-bars 33 and the latter being bent between theirends at 38 to clear each other.

The operating-levers 9 are provided at their upper portions with sockets39 for the reception of a movable handle or bar 40, which is adapted tobe transferred from one end of the car to the other to enable themechanism for raising and lowering the upper frame to be operated ateither end of the car. This construction obviates the necessity ofemploying transfer-cars or turn-tables for turning the car end for end.The handle or bar 10 is retained in the sockets by suitable catches 41,which may be constructed in any desired manner. When eitheroperating-lever is oscillated, the wedges will be simultaneouslyreciprocated, and the shiftable antifriction devices which support thewedges will enable the latter to move freely inward and outward. Theantifriction-wheels of the upper frame also permit the latter to beraised with a minimum amount of friction. The weight of the upper frameand the load of the car resting upon the upper seats will retain theparts in the position illustrated in Fig. 3 of the drawing s, and it isunnecessary to provide any locking mechanism for preventing the wedgesfrom accidentally moving inward. The construction for raising andlowering the upper frame also permits a low truck or car to beconstructed, thereby increasing the carrying capacity, as bricks can beconveniently loaded only to a certain height.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is
